A Current Literature Report on the Carcinogenic Properties of Ionizing and Nonionizing Radiation

Unknown authors

The report states there is virtually no scientific literature directly relating to carcinogenic effects of MW and RF radiation. The evidence comes from a WHO epidemiologic study reported by Zaret (1976) showing a possible correlation between MW-induced cardiovascular disease increase and a rise in cancer incidence. International exposure standards vary widely, from 10 mW/cm² in Western countries to 0.01 nW/cm² in the USSR and Poland, due to lack of definitive research on long-term low-level effects.

Microwave Techniques In Biological Research - Session XI

H. M. Altschuler

Temperature and humidity are controlled in the chamber surrounding the waveguide. The absorbed dose rate varies with animal movement, allowing qualitative stress monitoring. The authors note that microwave heating in tissues is often non-uniform and hot spots could occur in vital organs.

INVESTIGATION OF BIOLOGICAL OBJECTS IN HIGH FREQUENCY ELECTRICAL FIELDS

A. K. Mulatov, R. S. Stepanov, S. D. Kirlian, V. H. Kirlian

Strong pulsating high frequency fields with a small average amount of power may extract electrons from living objects without detrimental effects and are normally safe for living organisms. The magnitude of the autoelectric emission current depends only on the field potential and the electron work function, where the field potential is determined by the dielectric constant and geometry of the object, and the work function depends on physio-chemical causes.

Microwave Power for Biology and Medicine

Unknown authors

The Model 1326 signal generator covers 350 MHz to 10,475 MHz and provides up to 500 watts continuous wave and 1.8 kW peak pulsed power. Cober supplies microwave power packs from 1 kW to 50 kW at 915 MHz and 2450 MHz ISM bands.

MAGNETIC FIELDS IN BIOLOGY

Alexander Kolin

A heterogeneous magnetic field induced curvature in both roots and shoots, causing them to curve away from the plane of maximal field strength. A uniform magnetic field reduced molting failure in flour beetle pupae, with a 6.2 kilogauss field at 39.5°C having the same effect as a 15°C temperature drop. Nonhomogeneous magnetic fields applied to fruit fly pupae produced inheritable changes in development time that persisted for 30 generations. Magnetic field fluctuations near the human chest were detected and related to the ECG, and transient magnetic fields associated with nerve impulses were recorded.

Relaxation Parameters of a Suspension of Membrane-Covered Ellipsoids

D. W. C. Shen, H. P. Schwan

The derived formulas for ellipsoids agree with Fricke's results for low and high concentrations when aligned, but with random orientation they match only at low concentration and differ slightly at high concentration. By combining the homogeneous ellipsoid concept with complex conductivity, the authors obtained dispersion equations showing a low-frequency dispersion from the core and three higher-frequency dispersions from the membrane. The model assumes the membrane thickness is much smaller than the ellipsoidal axes, allowing the core and membrane contributions to be distinguished in the equations.

MICROWAVE EFFECTS ON HUMAN COLONY FORMING MARROW CELLS

Unknown authors

Researchers exposed marrow cells from three leukemia patients in remission to 2450 MHz continuous-wave microwaves at four power levels for 15 minutes. Sham exposures used the same chamber without microwave power. Colony formation was significantly reduced at 500 and 1000 mW/cm2 but not at lower power levels.

Measurements of electric and magnetic field strengths from industrial radiofrequency heaters

M. Hietanen, K. Kalliomäki, P-L. Kalliomäki, P. Lindfors

Researchers measured electric and magnetic fields from 35 plastic welding machines operating at 27 MHz with nominal powers of 0.5 to 35 kW. About 70% of the heaters exceeded the common standards of 200 V/m and 0.2 A/m, and 80% exceeded the Finnish proposed standard of 60 V/m and 0.2 A/m. At the worker's position, electric field strength above 190 V/m occurred in 66% of equipment, and leakage above the Finnish proposal of 60 V/m occurred in 94.3% of devices. Magnetic field strength above 0.5 A/m was found in 60% of equipment, and the Finnish proposal of 0.2 A/m was exceeded in 74% of cases.

THE INCREASE IN FLUID PRODUCTION DURING ULTRASHORT WAVE FLOW-THROUGH IN THE HEAD

H. C. Gloz

Tests on 15 patients using Siemens tube senders showed a lumbar fluid pressure rise from 5 to 52 mm that remained after the current was turned off. The most effective electrode distance was 25 mm with Schliephake electrodes. In two-thirds of cases systolic blood pressure dropped to 20 mm while diastolic pressure stayed constant. Retinal examination revealed venous filling and coiling within 30 seconds, arterial dilation by 1-2 minutes, and these vascular changes persisted for 1-2 hours after exposure.
